LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 663,277, dated December 4, 1900.

Application led May 23, 1900. Serial No. 17,753. (No model.)

To all whom t Wawy concern:

Be it known that I, LOUIS I-IORVATH, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Lawn-Sprinklers, of which the following is a specification.

My invention relates to sprinklers that are stationary; and the object thereof is to proro duce a sprinkler for use with hydrants which will dispense with the use of hose and at the same time will enable the operator to sprinkle a large surface of lawn. I accomplish this object by the device described herein I5 and illustrated in the accompanying drawings, forming a part hereof, in which- Figure I is a side view of my sprinkler attached to a hydrant with the supply-pipe broken away, an additional quadrant-elbow 2o being shown with nozzle attached thereto in dotted lines to illustrate vertical rotation of the nozzle. Fig. 2 is a central vertical sectional view on the line 2 2 of Fig. l to illustrate how the quadrant-elbow D may be rotated in coupling-nut E.

In the drawings, A is ahydrant, of ordinary construction, having a downwardly-projecting bib, to which is coupled a U-shaped pipe B. I preferably make the outer leg of the U 3o a little longer than the one coupled to the hydrant to elevate nozzle C above the hydrant. Nozzle C is attached to quadrant-elbow D, which is coupled to the outer leg of pipe B by coupling-nut E, which by unscrewing or turning elbow D backward permits nozzle C to discharge a spray, a sheet, or stream of water in any direction, depending on the construction of the nozzle. The curves in pipe B and elbow Dare arcs of a circle,

4o preferably of the same radius. By this construction the greatest freedom of flow of the water is obtained, and I have found by eX- periment that undertwenty pounds pressure a sprinkler thus constructed will from one hydrant Water more lawn" surface than can be watered with a piece of hose twenty-five feet long from the same hydrant, using the same nozzle. By the use of an additional quadrant-elbow intermediate nozzle C and elbow D the nozzle can be rotated vertically, 5o and thus enable the operator to sprinkle any part of the surface adjacent to the hydrant.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A sprinkler, comprising a U shaped member having one leg thereof longer than the other, the portions of which that unite the two legs forming a semicircle; a quadrant elbow-shaped member having a curve one- 6o half of that of the semicircular part of the U-shaped member attached to the longer leg of the U-shaped member by a coupling-nut adapted to permit of the rotation of the quadrant-elbow; anda nozzle attached to the other end of the quadrant-elbow.

2. The herein-described sprinkler, comprising the U -shaped pipe B, the legs of which are united by a semicircular-shaped portion adapted to be attached to a hydrant 7o by one of its legs; elbow D whose curve is one-half of that of the semicircularpart which joins the legs of the U -shaped member, adapted to be coupled with the other leg ofpipe B; and nozzle C, adapted to be coupled to elbow D, in combination with hydrant A.

In witness that I claim the foregoing I have hereunto subscribed my name, this 15th day of May, 1900, at Los Angeles, California.

LOUIS HORVATH.
